#Introduction Central to history is the world of work in the past, as known by occupational activities. Yet comparative research in this field is severely hampered by confusion regarding occupational terminology across time and space, within as well as between languages. To overcome this, we create an occupational information system that is both internationaland historical, and simultaneously links to existing classifications used for present-day conditions. The information system uses a historical international classification of occupations (HISCO) to combine various kinds of information on their tasks and duties in historical settings, as well as images on the history of work. Moreover it provides information on rankings of occupations (HISCAM) and we aim for other resources in the future. Not just occupational scales and measures, but also depictions and occupational descriptions available through images and texts.

Current version HISCAM 1.3.1 Feb 2021. HISCAM scales as per Lambert et al 2013. Indicate 'high' and 'low' positions of occupations for various time periods and countries. Here provided as Linked Open Data. Please cite us when using this data.


This is your workbench for historical occupations as all graphs from the historyOfWork are combined here. This version is dated Feb 2021. Use this dataset to retrieve HISCO and HISCAM scores for an incredible amount of occupations in numerous languages.

Data can be queried (obtained) via the SPARQL endpoint or via the example queries.

This is the latest dataset (feb 2021) that contains coded occupations (e.g. HISCO) that have been donated by the community.
